Abstract
X-ray diffraction in an orthorhombic crystal modulated by two transverse-displacement waves propagating along one of the crystallographic directions has been numerically studied within the framework of the kinematic approximation. Crystal models are considered that allow the superposition of the displacement waves or the coexistence of domains modulated by the displacement waves with different parameters. It is shown that the formation of peaks additional to the satellite ones is possible not only due to the superposition of the displacement waves, but also due to a certain correlation of the displacement waves in each domain.
